A mum today made an emotional appeal for help in catching her son's attackers.

Christopher Scales, 17, was walking a dog with three friends in Bowlyn Close, Sunderland on December 7 when two men approached and without warning stabbed him twice in the back and slashed him across the ear.

The knife narrowly missed his kidney and Christopher spent a day in intensive care and a total of two weeks in hospital.

Today his mum Gillian, 37, made a plea to catch his attackers before someone else's child is either seriously hurt or even killed.

Gillian said: "I looked on the Internet the other day and saw someone died from a stab wound to the leg. Christopher has been very lucky.

"This is the last hope of trying to get someone brought to justice for what they did. I wouldn't have wished this on my worst enemy."
